AI Is Supercharging Ransomware Attacks on Japan's Critical Infrastructure

Japan is facing a surge in ransomware attacks targeting critical infrastructure, and experts say artificial intelligence is making these cyberattacks easier to carry out. Ransomware is malicious software that locks a victim's computer or data until a payment is made. When it hits critical infrastructure—such as power grids, hospitals, or transportation systems—the impact can disrupt daily life for millions of people. The recent wave has raised alarms among security officials. Experts point to A.I. tools as a key factor behind the rise, because they help attackers launch more sophisticated strikes with less skill and effort. The full scope of the damage and the identity of the attackers remain unclear.
